As one can see, the inside of the Overflow Tank is old and rusty.  But we have a new Myers pump in it (Pump #3) and the tank holds water.  So even though it’s not in great shape, it still serves its purpose.

This valve is not connected to any piping, so ignore it.

This valve is frozen open and will not work, but it is part of Pump #3’s outlet piping.

Float switches to control Pump #3

Pump #3 cannot be seen

Look carefully and you can see the overflow pipe entering the tank from the Wetwell

Here’s a close-up of the float switches that control Pump #3:

ON float switch

 

OFF float switch

Note that the Overflow Tank should be essentially empty at all times.  But every couple of weeks it should be opened up and checked.

* This float switch was part of the old system when we used two pumps in this tank.
